We have put forth a long-term low-emissions development strategy (LEDS) that aspires to halve emissions from its peak to 33 MtCO2 e by 2050, with a view to achieving net-zero emissions as soon as viable in the second half of the century. This will require serious and concerted efforts across our industry, economy and society. We also need to rely on global advances in low-carbon technology and on increased international collaboration, to realise such an aspiration. Each thrust will contribute to our aspiration of halving our emissions. We will pursue all three vigorously to achieve this aspiration. The extent to which potential emission reductions from each thrust can be realised will become clearer in the coming years, as we gain experience from implementing our programmes, as technology evolves, and as the modalities for international collaboration become formalised.
