Heavy goods vehicles predominantly run on diesel. Here are three options for eliminating their emissions.
Nigeria needs more than trucks to achieve effective freight management.
In addition to transport, Nigeria needs to pay more attention to logistics and supply chain management.
Renewables form an ever-greater share of the electricity mix. But elsewhere in the energy sector – in transport, industry and buildings – emissions reduction is very slow.
Global fossil fuel emissions dropped by about seven per cent in 2020 compared with 2019. But a rebound is likely to occur when lockdowns ease up unless COVID-19 recovery packages focus on ‘green recovery.’

Several countries have made pledges to reduce their greenhouse gas emissions to zero by mid-century. But new research finds the remaining carbon budget will be depleted before we get there.
We’re on the road again. Getting enough COVID-19 vaccine to where it’s needed in a given time frame is the next logistical hurdle.
Electric vehicles would lower emissions, but if their lower running costs lead to increased car use that creates a whole lot of other costs for our cities.
The age of autonomous vehicles is edging closer to reality with the launch of a driverless taxi service in the USA.
Some new habits we’ve seen emerging during the pandemic could help us solve tricky problems like traffic congestion, which have challenged our cities for a long time.
NSW Minister for Transport and Roads Andrew Constance announces a move to the next stage of planning for the Western Harbour Tunnel and Beaches Link project in November 2019.
Once again, the state looks intent on pressing ahead with a huge road project without releasing a business case. Among the many concerns is the failure to look at lower-emission alternatives.
The continued upward trend in our second-biggest source of emissions is a result of government inaction on a transport mix dominated by trucks and cars and a lack of fuel-efficiency standards.
Widespread use of autonomous vehicles could increase or cut greenhouse gas emissions. It all depends on public policy.
The sweeping introduction of driverless cars could see more vehicles on the road, driving longer distances. But smart planning could solve some of transit-associated environmental and social problems.
Demonstrations against freeway construction in Melbourne included a street barricade erected in protest at the F19 extension of the Eastern Freeway.
Barricade! – the resident fight against the F19
Public protests eventually forced the scrapping of some proposed freeways in 1973. Today, we have another round of projects and people are protesting again, with good reason. Government should listen.
When politicians use selected modelling results to justify their decisions on contentious projects like Melbourne’s North East Link, the credibility of transport models suffers by association.
Transport modelling has been tarnished by its use to justify the predetermined projects politicians favour. But, if used more transparently, it’s a valuable tool for planning our future cities.
The Melbourne Transportation Plan included every freeway and major arterial road built in the city since 1969.
While called a transportation plan,
it was heavily skewed towards roads. We need the type of city-shaping thinking that underpinned the plan, but today’s plans must match 21st-century priorities.
The Australian and Victorian governments have both promised funding for a Melbourne Airport rail link, but a private consortium’s unsolicited proposal is also on the table.
Unsolicited market proposals are not transparently assessed. Infrastructure should be built to serve the public interest, not shaped by its private backers, but the checks to ensure this are broken.
A whole range of social and technological changes could revolutionise how we travel in the coming decades.
Car owners’ attachment to driving and the willingness of others to switch from public transport could confound rosy predictions for autonomous vehicles.
Scenarios based on a survey of Adelaide commuters and analyses of traffic flows show it’s possible the congestion could get worse in the transition to driverless vehicles.
In cities like Copenhagen that have good infrastructure for cycling it’s an established commuting option alongside road and rail.
A breakdown in the road or rail systems often causes commuter chaos in Australia. Some overseas cities are more resilient because they have other options – and our bicycle network could give us that.
If more of us were free to work from home, fewer of us would be stuck in traffic.

Two-thirds of surveyed workers work from home one day a week on average, but could do at least half their work out of the workplace. If they commuted less often, congestion could be greatly reduced.
Analysing big data can tell us how a big city ticks, including where suitable housing and jobs are, and how best to get to them.
We have learnt to be wary of big data, but it can also be your friend: one platform combines and analyses data about housing, jobs and transport to reveal very useful information about living in Perth.
