UN: Pandemic causes dip in building emissions

NAIROBI, Kenya, 19 October 2021: The economic consequences of the COVID-19 pandemic caused CO2 emissions from buildings and construction to fall significantly in 2020, but a lack of real transformation in the sector means that emissions will keep rising and contribute to dangerous climate change, according to the 2021 Global Status Report for Buildings and Construction.

The report, published by the UN Environment Programme-hosted Global Alliance for Buildings and Construction (GlobalABC), finds that in 2020, the sector accounted for 36% of global final energy consumption and 37% of energy related CO2 emissions, as compared to other end-use sectors.

While the level of emissions within the sector are 10% lower than in 2015, reaching lows not seen since 2007, this w333as largely due to lockdowns, slowing of economies, difficulties households and businesses faced in maintaining and affording energy access and a fall in construction activity. Efforts to decarbonize the sector played only a small role, the authors of the report said.

With large growth projected in the buildings sector, emissions are set to rise if there is no effort to decarbonize buildings and improve their energy efficiency, the authors said. In Asia and Africa, building stock is expected to double by 2050, they said, adding that global material use is expected to more than double by 2060, with a third of this rise attributable to construction materials.

“This year showed that climate change is an immediate direct threat to every community on this planet, and it is only going to intensify,” said Inger Andersen, Executive Director, UNEP. “The buildings and construction sector, as a major source of greenhouse gas emissions, must urgently be decarbonized through a triple strategy of reducing energy demand, decarbonizing the power supply and addressing building materials’ carbon footprint, if we are to have any chance of meeting the Paris Agreement goal of limiting global warming to 1.5C.”

Some progress, but not enough

The GlobalABC’s Global Buildings Climate Tracker found that there have been some incremental improvements in action to decarbonize and improve the energy efficiency of the sector.

In 2015, 90 countries included actions for addressing buildings emissions or improving energy efficiency in their Nationally Determined Contributions (NDCs) under the Paris Agreement. This number has now hit 136, although ambition varie, the authors of the report said.

Since 2015, an additional 18 countries have put in place building energy codes – a move that is crucial to shift emissions downwards – bringing the total to 80, the authors said. Local cities and governments have also developed codes, they said. Investment in energy efficiency rose to over USD 180 billion in 2020, up from 129 billion in 2015. Green building certification has increased by 13.9% compared to 2019, they said.

Overall, however, the report finds that these efforts are insufficient, both in terms of speed and scale. Other key findings of the report include: Two-thirds of countries still lack mandatory buildings codes; most of the increase in energy efficiency spending came from a small number of European countries; too small a share of finance goes into deep energy retrofits, and there is a lack of ambitious decarbonization targets in NDCs.

What comes next?

Energy demand in the buildings and construction sector is likely to rebound, as economic recovery efforts take hold and as pent-up demands for new construction are realized, the authors said.

By 2030, to be on track to achieving a goal of net-zero emissions by 2050, the International Energy Agency says that direct building CO2 emissions would need to decrease by 50%. Indirect building sector emissions will have to drop through a reduction of 60% in power generation emissions. To achieve these goals, the report finds, the sector has to take advantage of every lever.

While pandemic recovery spending has not sufficiently prioritized climate-friendly approaches to the level required, the authors said, there is still an opportunity to invest in decarbonizing our buildings while increasing their resilience:

  • Countries need to harness the sector’s transformative potential for achieving the energy transition.
  • Governments need to commit to further decarbonizing the power, as well as heating and cooling energy supply. This includes stepping up ambition in NDCs to include building decarbonization targets that contain the so-far largely overlooked embodied carbon and the emissions from the production of building materials.
  • The rate of growth of investment in building efficiency needs to double to over 3 per cent per year, and must expand beyond direct government investment to private investors.
  • Scope and coverage of building energy codes need to increase. All countries need to have in place mandatory building energy codes, and these would ideally address performance standards for building envelopes, design, heating, cooling, ventilation systems and appliances, and ensure links with integrated urban planning.

Buildings’ resilience needs to increase to futureproof our homes and workspaces. A typical building constructed today will still be in use in 2070, but the climate it encounters will have changed significantly.

  • The necessary interventions to reduce the climate impact of existing buildings should be combined with investing in adaptation and resilience measures.
  • In addition, both public and private sector need to seize the tremendous investment opportunities this sector offers – for example, through green bonds or through banks increasing green building construction and mortgage finance.

IEA releases ‘roadmap to net zero’ report

BERKELEY, California, 18 May 2021: The International Energy Agency (IEA) said it has published its first ever comprehensive roadmap to net-zero emissions by 2050. The report, it added, provides guidance for governments, companies, investors and the public on what is necessary to fully decarbonize the energy sector and lower greenhouse gas emissions to limit temperature rise to 1.5 degrees Celsius.

The report, it said, comes after it received widespread criticism for systematically underestimating the pace of adoption of clean energy technologies, such as solar and wind, and substantially overestimating their costs. Critics, it said, argued that IEA projections had effectively acted as support for the fossil fuel industry’s business-as-usual operations.

In a significant shift, the IEA said, it today recognizes that on a net-zero pathway there can be no investment in new fossil fuel supply. This, it said, includes oil, gas and coal projects. The IEA said, it confirms that with the introduction of policy to achieve climate stabilization at 1.5 degrees, the fossil fuel sector will face significant demand reduction.

Danielle Fugere, President, As You Sow, responding to the release of the report, said: “This new net-zero scenario from the IEA finally aligns with investor expectations and makes abundantly clear to fossil fuel companies that they must set net-zero targets, develop a clear transition strategy, and evolve in step with the decarbonizing global economy. Standing in the way of progress is no longer acceptable for companies’ own enterprise success or for the global economy.”

Daniel Stewart, Senior Research Associate, As You Sow, said: “Until now, the IEA’s research has been used to play down transition risks faced by the fossil fuel industry and as a support for inadequate energy and climate policy. IEA’s new scenario firms up what investors already knew about the steps needed to achieve climate stabilization by mid-century. It demonstrates without a doubt that it is difficult but absolutely possible to contain the catastrophic impact of runaway climate change, and signals major disruption on the horizon for industries reliant on fossil fuels.”

JCI named to FT European Climate Leaders list

CORK, Ireland, 18 May 2021: Johnson Controls (JCI) said it has been named to the inaugural FT Climate Leaders in Europe list.

Europe’s Climate Leaders 2021 is a list of companies across Europe that have shown the highest reduction of their emission intensity – that is, core greenhouse gas emissions in relation to revenues, between 2014 and 2019. Johnson Controls reported that it was one of only 300 companies selected from 4,000 across Europe.

“We are extremely proud to be recognized by the Financial Times as a European climate leader,” said George Oliver, chairman and CEO, Johnson Controls. “Sustainability has long been at the heart of everything we do, and it is an honor to be included on this prestigious list. With COP26 approaching at this critical moment in the battle against climate change, it is important that companies continue to play their part in cutting emissions and delivering clean, sustainable solutions across the entire value chain.”

According to JCI, companies on the list – compiled by research firm, Statista – were invited to submit emissions reported following the emission categories of the greenhouse gas protocol (scope 1, 2 and 3). In addition, Statista scrutinized publicly available data, mainly from financial and non-financial reports as well as from CDP (formerly the “Carbon Disclosure Project”).

Although JCI reports all three emissions scopes, the ranking only considers scope 1 and scope 2 emissions, since not all companies publish their scope 3 emissions, it said. Since 2002, JCI said, it has reduced its emissions intensity by more than 70% – equivalent to the carbon sequestered by 17,000 acres of forest. The company said it has also helped its customers save more than 30.6 million tonnes of CO2 globally and $6.6 million through guaranteed operational savings.

At the European level, JCI said, it has been effectively supporting the EU’s ambition to become carbon neutral by 2050. The European Commission recently committed to at least 55% cuts in greenhouse gas emissions (from 1990 levels) by 2030 under the European Green Deal. Decarbonizing Europe’s building stock through the European Commission’s Energy Performance of Buildings Directive has a crucial role to play in this effort – 40% of greenhouse gases come from buildings, the company said.

According to JCI, digitalization has been recognized as a key enabler for the building renovation wave in Europe and the rest of the world. Already, JCI said, it has been deploying its OpenBlue digital platform for optimizing buildings sustainability across its entire value chain – drastically improving the company’s own environmental impact and helping customers consume less energy, conserve resources and identify pathways to achieving healthy, net zero carbon communities.

Katie McGinty, Vice President & Chief Sustainability, Government and Regulatory Affairs Officers, JCI, said: “We are making positive change within our own corporation and believe we are uniquely positioned to help customers and suppliers achieve their sustainability goals. By driving global change, we are ultimately creating an environment for healthy people, healthy places and a healthy planet.”

JCI said it is also helping meet the growing demand for energy-efficient technologies. It said it has provided heat pump solutions for customers at more than a dozen district heating and cooling applications in Denmark, Finland, France, Germany, Italy and Norway.

Heat pumps, it said, have an important role to play in decarbonizing buildings and industry. They have long been in the DNA of industrial refrigeration – utilised in food and beverage, dairy and other process industries for reclaiming low-temperature waste heat and turning it into low-cost, high-temperature heat.
