Working where we have the most impact
We determine where to engage by monitoring where the achievable tons of abatement potential are greatest, and what the near-term policy reform opportunities are. Our priority is to avoid catastrophic increases in buildings sector emissions so that global warming stays well below 2oC.
In 2020 the construction and operation of the buildings sector contributed around 11.7Gt CO2 of GHG emissions. Five key markets; China, USA, EU, India, and ASEAN together contributed almost 60% of this total. In advanced economies such as the EU and USA, most of the emissions abatement opportunity comes from deep energy efficiency renovation of existing buildings, 50% of which will still be standing in 2050. However, the majority of new GHG emissions will come from emerging and developing economies which will contribute 80% of all new construction projected between now and 2050. Globally we add the equivalent of the surface area of Paris in new construction every week. Most of the new demand is for housing.
Many of these economies have few or no building energy regulations, or policies that support decarbonisation, particularly for housing. Where policies are in place, implementation and accounting for their economic and health benefits remains a challenge. So, it is imperative that we engage now to establish the policies that avoid significant emissions growth by ensuring that new construction is net-zero emissions or as close to this as possible. That’s why GBPN has since 2019 been implementing our ‘Policy Strategy for Decarbonising Buildings in Asia’ with a particular focus on policies that can avoid GHG emissions from new housing in India and Indonesia.
