The realities of a lower carbon world

Climate change remains a hugely emotive topic around the world, with awareness and activism both surging in recent months – and today marks the start of the first London Climate Action Week.

But while many might be aware of the Paris Agreement to limit global average temperatures and the UK’s very welcome recent pledge to be carbon neutral by 2050, it remains to be seen how far these laudable goals are understood in practical terms.

Getting to zero emissions requires halving current global emissions by 2030, halving again by 2040 and then halving/offsetting the rest by 2050. The faster we do this, the better the outcome. To be clear, current regulatory demands would produce nowhere near that kind of reduction and we therefore predict much tighter global regulation to reduce emissions in the years ahead. This is likely to create opportunities for companies on the right side of this energy transition and we will be covering some of these in an article later this week.

To try to make sense of this, we have looked to see what this net zero emissions target means for the average person in the UK, who directly emits 10 tonnes of carbon dioxide a year. Broken down, approximately 5.7 tonnes of this is from transport, 2.7 tonnes from heating with natural gas and a further 1.6 tonnes come from the electricity used in the home.

Personal direct emissions from travel & home (uk average) 

If people are so minded, there are a few simple steps to reduce these figures almost immediately.

Taking electricity first, moving to a 100% renewable provider (of which there are a growing number in the UK) can be done instantaneously and, for the most part, for the same price as existing tariffs. This ensures all the electricity you need is supplied to the grid via renewable sources and moving to such a provider reduces the annual emission by 1.4 tonnes.

On the heating side, ensuring your home is properly insulated can cut another 0.5 tonnes off that annual emission level – and while this work will mean an initial outlay of a few hundred pounds, the saving on future heating bills should more than offset that in fairly short order.

Coming finally to the transport question, electric vehicles (EVs) will become significantly cheaper as all the main car manufacturers are set to bring more affordable EVs to market in the next two years. The charging infrastructure is also being expanded at pace. As these two major barriers to adoption are reduced, we believe EVs will take a meaningful share of the car market.

Moving to an EV shaves a further 1.7 tonnes off the annual level, and again, while there is a cost question at the purchase stage, there are considerable ongoing savings versus running a petrol or diesel car.

According to data from British Gas, for a small family hatchback over 10,000 miles the average price per mile is 4.1 pence for an EV versus 18p for a petrol car, while a large diesel vehicle is considerably more expensive. Figures do vary according to car model and various other factors (including charging at home versus a public point).

A final measure is cutting down airline flights where possible and, as a last resort, offsetting the impact where you have to travel, which can take another 1.7 tonnes off the total. There are two main types of offsetting projects: investing in renewable energy projects or for the more horticulturally minded out there, either stopping existing trees being cut down or planting new ones.

If we take all these measures together, it is remarkably easy to more than halve the average person’s direct carbon emissions in the UK. In this example, it removes a total of 5.4 tonnes off the average annual emission of 10 – and with the possible exception of changing cars, these are all steps that can be taken in a few days, without excessive cost and with very little discernible impact on our daily lives.

Reduced personal direct emissions

Overall then, the challenge to reduce emissions is huge and broadly misunderstood and underestimated. It will affect many parts of our economy, not just energy generation but also transport and how we heat and cool buildings as well as industry. But this lower carbon future can be a positive one and is a massive opportunity to rethink and better manage resources as well as consider how we can help people who need decent work to get behind the products and services enabling the transition. It could easily be much better than what we have now.

Key Risks

Past performance is not a guide to future performance. Do remember that the value of an investment and the income generated from them can fall as well as rise and is not guaranteed, therefore, you may not get back the amount originally invested and potentially risk total loss of capital. The majority of the Liontrust Sustainable Future Funds have holdings which are denominated in currencies other than Sterling and may be affected by movements in exchange rates. Some of these funds invest in emerging markets which may involve a higher element of risk due to less well regulated markets and political and economic instability. Consequently the value of an investment may rise or fall in line with the exchange rates. Liontrust UK Ethical Fund, Liontrust SF European Growth Fund and Liontrust SF UK Growth Fund invest geographically in a narrow range and has a concentrated portfolio of securities, there is an increased risk of volatility which may result in frequent rises and falls in the Fund’s share price. Liontrust SF Managed Fund, Liontrust SF Corporate Bond Fund, Liontrust SF Cautious Managed Fund, Liontrust SF Defensive Managed Fund and Liontrust Monthly Income Bond Fund invest in bonds and other fixed-interest securities - fluctuations in interest rates are likely to affect the value of these financial instruments. If long-term interest rates rise, the value of your shares is likely to fall. If you need to access your money quickly it is possible that, in difficult market conditions, it could be hard to sell holdings in corporate bond funds. This is because there is low trading activity in the markets for many of the bonds held by these funds. Mentioned above five funds can also invest in derivatives. Derivatives are used to protect against currencies, credit and interests rates move or for investment purposes. There is a risk that losses could be made on derivative positions or that the counterparties could fail to complete on transactions.
