Energy outlook bad for emissions

Carbon emissions from energy consumption will grow by 1% a year between now and 2035, according to new analysis by energy company BP.
Its latest annual energy outlook warns that the trajectory for carbon emissions is significantly above the path scientists recommend. “The most likely path for carbon emissions, despite current government policies and intentions, does not appear sustainable,” writes BP chief executive Bob Dudley.
The report forecasts that, by 2035, global carbon emissions will be 18 billion tonnes above the International Energy Association’s 450 scenario. In this context, restricting the global increase in temperature to 2°C requires limiting the concentration of greenhouse- gases in the atmosphere to around 450 parts per million of CO2.
The BP report says that abating emissions will require additional steps by policymakers beyond those already assumed. It advises that no one option is likely to be sufficient on its own, and multiple options, ranging from increases in renewables to improvements in vehicle efficiency, will need to be pursued.
BP says policymakers must implement measures that lead to a “meaningful” global price for carbon. This would provide the right incentives for the most cost-effective investments to be made, says the report.
The oil and gas firm forecasts that energy demand will rise 37% over the next 20 years, mostly in non-OECD countries. It also predicts a change in the global energy mix over the next two decades, with increases in coal consumption declining sharply, and natural gas replacing it as is the fastest growing fossil fuel. The fastest growth will be in renewables, with capacity rising by around 6.3% a year.
Among non-fossil fuels, renewables, including biofuels, will gain share rapidly, from around 3% today to 8% by 2035, says BP. It forecasts that the overall shares of nuclear and hydro will decline, but the scaling up of renewables will lift the aggregate non-fossil share from 32% in 2013 to 38% by 2035.
Demand for fossil fuels will peak by 2025 if all national net-zero pledges are implemented in full and on time, the International Energy Agency (IEA) has forecast.
The Green Homes Grant is set to deliver only a fraction of the jobs and improvements intended, leading to calls for more involvement from local authorities in future schemes.
COVID-19 recovery packages have largely focused on protecting, rather than transforming, existing industries, and have been a “lost opportunity” for speeding up the global energy transition.
Half of the world's 40 largest listed oil and gas companies will have to slash their production by at least 50% by the 2030s to align with the goals of the Paris Agreement, new analysis has found.
None of England’s water and sewerage companies achieved all environmental expectations for the period 2015 to 2020, the Environment Agency has revealed. These targets included the reduction of total pollution incidents by at least one-third compared with 2012, and for incident self-reporting to be at least 75%.
The UK’s pipeline for renewable energy projects could mitigate 90% of job losses caused by COVID-19 and help deliver the government’s ‘levelling up’ agenda. That is according to a recent report from consultancy EY-Parthenon, which outlines how the UK’s £108bn “visible pipeline” of investible renewable energy projects could create 625,000 jobs.
Billions of people worldwide have been unable to access safe drinking water and sanitation in their homes during the COVID-19 pandemic, according to a progress report from the World Health Organisation focusing on the UN’s sixth Sustainable Development Goal (SDG 6) – to “ensure availability and sustainable management of water and sanitation for all by 2030”.
